I'd like to create a temporary table in SQLAlchemy. I can build a CREATE TABLE
statement with a TEMPORARY
clause by calling table._prefixes.append('TEMPORARY')
against a Table
object, but that's less elegant than table.select().prefix_with开发者_运维知识库()
used to add a prefix to data manipulation language expressions.
Is there an equivalent to .prefix_with()
for DDL?
No, prefix_with()
is defined for SELECT and INSERT only. But convenient way to add prefix to CREATE TABLE statement is passing it into table definition:
t = Table(
't', metadata,
Column('id', Integer, primary_key=True),
# ...
prefixes=['TEMPORARY'],
)
